DONNELSON'S CAVE.--"The mouth of the cave is found at the head of a deep gorge worn through the limestone by a good-sized stream which flows from the cave and down the gorge to the broader valley beyond. Many centuries ago the cave extended the full length of the gorge, and the waters of the stream flowed directly from its mouth into the valley. The roof of the underground channel finally became so thin that it collapsed, the gorge was then started, and as the centuries went by grew in length, the cave becoming ever shorter by the continued falling of the roof. "Three passages open directly into the mouth of the cave. The right hand passage has the level of its floor about 5 feet above that of the entrance, while the opening on the left is 12 feet above the level of the stream and very difficult to enter without a ladder. The middle passage extends straight back from the common vestibule or main entry. The latter is 25 feet long, 21 feet high, and 18 feet wide, but at its farther end is reduced to the narrow middle passage between great masses of limestone. The water in this passage is waist deep and explorations must be made by wading or in a light canoe. One hundred feet within is a magnificent cascade, where the stream rushes and leaps down a narrow passage with such violence that the noise is plainly heard at the entrance. "The right-hand passage for the first 100 feet is about 10 feet high by 15 wide, with a clay bottom and a roof on a level with that of the vestibule. It then expands into a large room, 230 feet long and 40 feet wide, which lies east and west at right angles to the entering passage. This narrows at the west end to 20 feet, and at one point the outer air flows in through a small opening in the roof. From near the small end of the room a narrow passage starts off to the southward and can be traveled for 200 feet, when it becomes too small for further advance. Along this passage a small stream flows, disappearing through a hole in the floor near the entrance to the larger room. Other than this, both right and left passages leaving the main entry are dry. "The passage at the left of the main entrance to the cave is about 150 feet long by 20 broad, and contains no points of especial interest." [W.S. Blatchley.] It may be added to the above description that a heavy rain causes a rapid rise of several feet
